SPECIFICATION forming part of Letters Patent No. 624,068, dated May 2, 1899.

Application filed J auuary 5, 1899.

To all whom, it new concern: 7

Beit known that I, EUGENE MOREAU, a citizen of the United States, residing in the borough of Manhattan, city, county,and State of 5 NewYork,havein vented certain new and useful Improvements in Containers for Oarbid, of which the following is a specification.

My invention relates to a container for calcium carbid that is adapted more especially to for use in bicycle-lamps. Heretoforeit has been the general practice to supply the carbid used in this class of lamps in packages known as cartridges. My invention is designed especially to take the place of these packages and to permit the user buying carbid in bulk and to place any desired amount of carbid in the lamp within the capacity of the container.

I will describe a container embodyingzmy invention and then point out the novel features thereof in the claims.

In the accompanying drawings, Figure l is a vertical sectional view of a lamp, showing a container located therein embodying my invention,which is also in vertical section. Fig. 2 is a vertical sectional view of a container embodying my invention.

Similar letters of reference refer to corresponding parts in the two figures of the drawings.

A represents the casing of the lamp, which comprises a water-reservoir a, and a chamber a, in which chamber a container for carbid is adapted to be placed. The chamber a is provided with a detachable bottom (1 which enables the container to be inserted in the chamber a, and the bottom a has attached to it a spring a, which forces the container upward in the chamber.

Between the reservoir a and the chamber a- I locate a closure D, which forms a valveseat. Extending through this closure is a passage-way a for water, which passage-way is controlled by a valve a. A pointed extension a is provided on the closure D. A channel is formedin this extension, which is a continuation of the passage-way (L The extension forms a direct feed to the container and prevents the water from creeping over adjacent parts through capillary attraction.

b'erial No. 701,176. (No model.)

d represents a perforated tube inclosing the valve a and d a filtering medium surrounding the tube cl. One end of the tube dis inserted in a screw-threaded opening (1 in the closure D, while at the other end of the tube a perforated funnel d is provided. The funnel carries a milled wheel 01, which serves to ad- .j ust the tube d vertically and with it the valve a. The valve'a is held in the tube d, so as to move with it, by means of a cylindric portion d.

a represents a vent-cap which permits the .escape of air from the reservoir when it is being filled'with water.

0 represents a reflector supported from the casing, and c a burner which is at one end of a gas-passage c, the other end of the passage being in communication with the chamber a.

B represents the container for carbid. Its

body I) is preferably cylindrical and is proent material 19 is preferably provided within this tube.

The top I) is provided with a funnel portion Z), which when the top is in position extends into the tube b The funnelis also so arranged as to have the extension a extend into it.

12 represents a disk located within the body 17 and supported from the top I) by means of a spring 19 This spring is adapted to compensate for the swelling of the carbid. Disks 1) of absorbent material are provided within the body on the top and bottom of the carbid. The lower disk may be arranged as shown in the drawings.

The disk Z) and absorbent disks b are each provided with a central opening, through which the perforated tube extends.

Perforations D are provided in the top I), through which the gas generated within the container escapes into the chamber a.

Z) represents a head on the body I), which, besides serving as a rest for the top, serves also to indicate the greatest height that the container should be filled with carbid.

The operation of the device is as follows: The bottom a? is detached from the chamber a and the container removed. It is filled to any desired height with carbid, preferably not higher than the bead Z), and the top I) then replaced. The container is then placed in the chamber a and the bottom attached to the chamber. The spring (LG, carried by the bottom a forces the container upward, so as to have the extension (6 project into the funnel Z). Vater escaping from the reservoir is conducted by the extension into the container, where it passes through the perforations in the tube 1) to attack the carbid. The gas resulting escapes into the chamber and to the burner, where it is consumed. As the carbid swells it is confined within the container by the absorbent disk b and disk 11 -\Vhat I claim as my invention is 1. A containerforcarbid comprisingabody,

a removable top and bottom for said body, a perforated tube carried by said bottom and extending within the body, and a disk within said body yieldingly supported from said top substantially as described.

2. A container for carbid comprising abody, a removable top and bottom for said body, a perforated tube carried by said bottom and extending within the body, a disk within said body yieldingly supported from the top, and absorbent disks adapted to be located at the top and bottom of the carbid within the container, substantially as described.

3. A container forcarbid comprising a body, a removable top and bottom for said body, a perforated tube carried by said bottom and extending within said body, and a funnel portion carried by said top that projects within said perforated tube, substantially as deseribed.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses,

EUGENE MOREAU. \V i tnesses:
